Dysplasia in colonic sessile serrated adenomas (SSAs)/sessile serrated polyps often shows loss of MLH1 expression as determined with immunohistochemistry, but the significance of loss of MLH1 expression in non‐dysplastic crypts in these polyps is less well studied. The purpose of this study was to evaluate the prevalence of loss of MLH1 expression in non‐dysplastic crypts in SSAs, and to evaluate its significance with regard to progression of these polyps.
